When I use "hdparm" to examine the settings of all of my hard drives
in 2.2.19 and 2.4.x, the only difference is that the 2.4.x kernel
sets multcount to 16 by default while 2.2.19 sets it to 0 by default.
Setting multcount to 0 with 2.4.x for all my drives does not help -- I
still get the errors as soon as I start trying to do lots of disk
activities.
Here's an example of the errors I got in the last go-around before I
gave up on 2.4.16-pre1 (with irrelevant fields removed to make the
syslog output easier to read):
22:58:56 hde: timeout waiting for DMA
22:58:58 hde: dma_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
22:58:58 hde: dma_intr: error=0x84 { DriveStatusError BadCRC }
22:58:59 hde: dma_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
22:58:59 hde: dma_intr: error=0x84 { DriveStatusError BadCRC }
22:58:59 hde: dma_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
22:58:59 hde: dma_intr: error=0x84 { DriveStatusError BadCRC }
22:58:59 hde: dma_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
22:58:59 hde: dma_intr: error=0x84 { DriveStatusError BadCRC }
22:59:19 hde: timeout waiting for DMA
23:00:23 hde: timeout waiting for DMA
23:00:24 hde: timeout waiting for DMA
23:00:24 hdg: timeout waiting for DMA
23:00:31 hdg: timeout waiting for DMA
23:00:33 hdg: status error: status=0x58 { DriveReady SeekComplete DataRequest }
23:00:33 hdg: drive not ready for command
I've seen people mention in comp.os.linux.development.system that the
BadCRC error may indicate a cable problem. However, (a) I'm pretty
certain that I'm using Ultra66 cables for both hde and hdg, and (b) if
that's the problem, why don't I get the same errors with 2.2.19?
As for (a), I believe I've got the right cables because I checked when
I installed them and because the controller (Promise Ultra66)
recognizes both hde and hdg as Ultra-capable drives when it starts up
(which it wouldn't do if I didn't have the correct cables -- I know
this because it wasn't doing it when I didn't have the correct cables
;-).
As for (b), is 2.4.x more paranoid about and/or better at checking
CRCs than 2.2.19 was?
I should note that when the errors shown in the log above are
happening, I'm also seeing "Lost interrupt" messages on my console for
hde or hdg.
Appended below are the pertinent details about the two drives that are
giving me trouble. If anyone can offer *any* insights into what I can
do to debug and solve this problem, I'd much appreciate it. Until I
can solve it, I'm stuck using 2.2.x, which is unfortunate since (a)
Andre has stopped maintaining his IDE backport patches for new 2.2.x
versions and (b) there's functionality in 2.4.x that I want to use.
Thank you,
Jonathan Kamens
